Traffic Signals
Traffic signals control the right of way and provide for a smooth, orderly flow of traffic. If a signal appears dark, such as during a power failure, you should stop as if there are stop signs in all directions. When a traffic signal is out of order and flashes yellow or red, you must obey that signal.
Steady Red
A steady red signal means stop and remain stopped until the signal changes.
You are allowed to make the following turns on red after coming to a complete stop unless a sign or police officer states otherwise:
- When entering a two-way road, you may turn right.
- When entering a one-way road, you may turn right or left in the direction of the one-way road.
Flashing Red
A flashing red signal is treated the same as a stop sign.
Red Arrow
A steady red arrow means stop and remain stopped until the signal changes, except for allowed turns on red. The same turns allowed for a steady red signal are allowed for a red arrow.
Steady Yellow
A steady yellow signal warns you that the signal is about to turn red. Stop before entering the intersection. If you cannot stop safely, drive carefully through it.
Flashing Yellow
A flashing yellow signal means slow down and proceed with caution.

A green signal means all movements—straight ahead, left or right turns—are permitted, unless prohibited by a sign. Left turns must first yield to pedestrians and oncoming traffic. Right turns must first yield to pedestrians.
Green Arrow
A steady green arrow means you have the right of way and may make the movement indicated by the arrow.
